Rheologists on Staff

Dr. Paul Tong, Ph.D. in Materials Science from University of Wisconsin-Madison with a strong academic and industrial background in rheology. His expertise also includes polymer characterization, processing and mechanical behavior. A 25 year industrial research career has focused on applying rheology to the characterization and processing of complex materials. Experienced with a wide range of rheological techniques, highlighted by novel methodology development, Paul has worked hands-on with polymer melts, polymer solutions, suspensions, inks and adhesives.

Peter K.W. Herh, Graduate degree in Polymer Physics and Materials Science from Rutgers University with more than 40 years rheological experience covering the full spectrum of materials and measurement techniques. Peter’s work history in the field of rheology covers both academia at Rutgers University, and industrial at Rheometrics, Bohlin Reologi, and ATS RheoSystems.

Dr. Jared A. Tatum, Ph.D. in Chemical Engineering from Clemson University. Jared has worked with a variety of different rheological systems including elastomer and thermoplastic melts, rubber compounds, particle composites, and polymer solutions. His 10+ years experience in the field of rheology is extensive, with a concentration on rotational and capillary rheology measurements, extensional viscosity, and property/structure relationships. An additional area of interest is optical techniques for measuring flow fields such as Particle Image Velocimetry (PIV) and their applications to understanding how different fluid properties affect flow fields.

Dr. Tien Dao, Ph.D. in Chemical Engineering from Texas A&M University with research on polymer surface and polymer rheology. Post Doctorate at Michigan State University with research on nanoparticles suspension in polymer melts and their effect on thermal and rheological properties. Tien's areas of expertise also include thermal analysis, and polymer characterization and processing. Throughout a 10+ year rheology career, his work experience covers a wide range of polymeric rheological research, coupled with practical experience with polymer melts, polymer solution, and suspensions. Additional areas of interest are polymer birefringence and polymer-surface interaction and their flow properties.

Dr. Allan X. Ye, Ph.D. in Chemical Engineering from Monash University (Australia), focusing on the shear and extensional rheology of polymers including polymer blends, long-chain-branched polymers and block copolymers. During his postdoctoral career at the Levich Institute, City College of New York, Allan was involved in several projects covering the rheology of concentrated suspensions, fumed silica gels and granular materials. Throughout his 10+ years rheological experience, Allan’s research focused on the relationship between the microstructure and macroscopic properties of materials, with a focus on optimizing the processing of complex fluids.
